Reliance Projects & Property Management Services Field Engineer Interview Questions, Process, and Tips

SINR stands for Signal-to-Interference-plus-Noise Ratio. It measures the quality of a wireless communication signal.

• SINR is calculated by measuring the strength of the desired signal, interference, and noise in a communication channel.

• A higher SINR value indicates better signal quality and less interference.

• A good SINR value is typically above 20 dB, while a bad value is below 10 dB.

• SINR is important in determining the...read more

Interference is the disruption of a signal caused by other signals or environmental factors.

• Interference can be caused by electromagnetic interference (EMI) from nearby electronic devices.

• Physical obstructions like buildings or trees can also cause interference.

• Interference can result in poor signal quality or loss of signal altogether.

RSRP actual value is the Received Signal Reference Power, a measurement used in wireless communication to determine signal strength.

• RSRP is measured in dBm (decibels per milliwatt)

• It is used in LTE networks to determine the quality of the signal received by a device

• A higher RSRP value indicates a stronger signal strength, while a lower value indicates a weaker signal

• RSRP values typically range from -140 dBm to -44 dBm

Reliance Jio uses the 2300 MHz band for 4G services.

• Reliance Jio primarily operates on the 2300 MHz band for 4G services.

• The 2300 MHz band is also known as the 2.3 GHz band.

• This band provides high-speed data services to Jio customers.

GPON (Gigabit Passive Optical Network) is a fiber optic technology that enables high-speed data transmission over long distances.

• GPON is a point-to-multipoint network architecture.

• It uses passive optical splitters to divide the optical signal to multiple users.

• GPON supports downstream and upstream data transmission.

• It provides high bandwidth and is capable of delivering services like internet, voice, and video.

• GPON is ...read more
